Kepler-186f is an exoplanet that orbits a star other than the Sun. Its star is the red dwarf Kepler-186. It is the first planet to be discovered that orbits its star at a distance similar to Earth’s distance from the Sun. If Kepler-186f is approximately 5.4 x 1010 meters from Kepler-186, how long does it take for light from the star to reach the exoplanet? The speed of light is 3.0 x 108 m/s
